Description

Safety epidemic prevention elevator and use method thereof

Technical Field

The invention relates to the field of elevators, in particular to a novel coronavirus epidemic prevention contact-free safety elevator and a using method thereof.

Background

The new coronavirus epidemic outbreaks worldwide, which is still severe at present, are most likely to be transmitted by close contact with infected persons. In addition indirect contact also leads to viral transmission, expert laboratory tests have shown that new coronaviruses can survive for hours to days on plastic and stainless steel surfaces, and in addition viruses similar to those responsible for major outbreaks of epidemic disease have been found to be most suitable for survival on smooth hard surfaces.

People are taking the elevator, and many people are received in the confined elevator car in less space relatively, if do not carry out timely effectual disinfection to the interior air of car, the virus passes through air propagation very easily, and conventional ventilation scheme is inefficient, and the filter effect is poor. When the user sends an instruction to the elevator system through the entity key, the potential safety hazard of virus transmission also exists. In addition, viruses may adhere to the inner wall of the car and survive for a long time, and the inner wall of the car is cleaned and disinfected manually, so that the efficiency is low and the time is short.
